| 摘 要： | 本文采用弹性-粘塑性模型对反平面剪切扩展裂纹问题进行了研究。文中通过对动态扩展问题和准静态扩展问题的分析得到了各自的渐近解,并且证明了准静态扩展解是动态扩展解的特殊情况,从而使二者统一起来。

| Abstract: | Adopting an elastic-viscoplastic model, the asymptotic problem of mode Ⅲ moving crack-tip filld is investigated. This paper gives the forms of all asymptotic solutions through the analysis of the dynamic crack propagation and quasi-static crack growith problems, and proves that the quasi-statically growing crack solution is the special case of dynamic propagating solution. |

| Keywords: | dynamic propagation quasi-static growth viscosity coefficient |
